snrerme DEVICE.

Application filed April 1a, 1928. Serial No. 269,759.

As clearly disclosed in the above mentioned' patent, it has been customary to extend a cross-piece or solid wooden clamp bar across the top of the box beingshippe I and to provide rods forconnecting the free end of. the clamp bar to the floor,.the rods being extended through the ends of the clamp bar and having threaded projecting upper ends on which nuts are applied to secure the clamp bar in place. The use of these solid wooden clamp bars ,has been found objectionable for several reasons, among which may be noted excessive weight, lack of efiicient action in aiding to prevent 2 shifting of the box on the floor, and the presence of objectionable projecting u per ends of the connecting rod, extending a ove the clamp bar.

An important object of the present invention, t erefore, is to provide an improved shipping device of the above kind by means of which the above mentioned objections are overcome in an eflicient and economical manner.

A more specific object of the invention is to provide "an improved box securing means of the above'kind including corner irons adapted to engage the upp'er corners of the box, and a connecting rod adapted to connect 40-the corner irons and extend across the top of the box, whereby the top of the latter is firmly gripped through the medium of a construction eliminating the use of the objectionable clamp bar.

Still another object is to provide a form of corner .iron of the above kind which is simple in construction and economical to 'manufacture, and means by which rods may be used for connecting the corner irons to the floor without the objectionable projecting of the upper ends of the latter rods abovethe top \of the box and the corner IIOD.

A still further object is to provide for convenient adjustments to enable the box to be firmly secured .upon the floor, and to provide simple and efficient means for securing such adjustments after the same are made.

The invention consists in the novel form, combination and'arrangement of parts hereinafter more fully described, shown in the accompanying drawing and claimed.

-In-the drawing: i

Figure 1 .is a fragmentary perspective v1ew showing a box secured upon the floor of a freight car by a means embodying the present invention;

Figure 2 is an enlarged. top plan view of one of the corner irons forming part of the shipping device shown in Figure 1;

igure 3 is an thereof;

Figure 4 is a side elevationalview of the same looking toward the right of Figure 3;

Figure 5 is a fragmentary: section taken on line 5- 5 of Figure 4;

Figure 6 is a fragmentary section taken on line 66 of Figure 4; and

Figure 7 is a plan'view of the blank from which the corner iron is formed.

For pur oses of illustration,

edge elevational view only a single box 5 is s own positioned upon the floor 6 of afreight car or the like, and; means, such as'members provided with oppositely dlsposed projections, may be positioned between the adjacent faces of the box and floor to prevent shifting of the box as *is disclosed in the above mentioned-patent.

The present invention has more particular reference to an improved means for securin the box against vertical movement or 110 ding it down on the floor 6 so as to preventing shifting of the box also aid in on the floor. This means generally consists of a palr of corner irons or bearer grips 7 adapted to fit upon and engage the upper side corners of the box 5, a rod 8 extending across the top of the box and connecting the corner irons 7, and further rods 9 connecting the corner irons 7 to the floor 6 to secure the'box 5 firmly upon the floor.

As shown, each corner iron is formed from a single strip of bar iron of rectangular form and uniform width from end to end as illustrated in Figure 7, the intermediate portion 10 of the stripjbeing bent intermediate its ends upon a transverse line 11 into angular form as shown clearly in Figure 3 to present portions disposed at right angles to each other and adapted to flatly engage the top and side faces of the box at the upper side corner of the latter as clearly illustrated. In this way the corner iron is. adapted to snugly fit and bear upon the corner of the box so that when the two cooperating corner irons are connected and drawn together, they may be connected to the floor by the rods 9 so as to most eflectively secure the box against'lateral as well, as longitudinal and upward displacement.v 'Each end of the strip from which the corner iron is formed is also bent'upon a pair of spaced parallel transverse. lines 12 and 13 to provide a flange or ear 14 projecting outwardly at right angles to the adjacent arm of the angular intermediate portion 10, and a resilient free end portion 15 disposed at an acute angle to and projecting inwardly from the outer end of the flange 14 to a point'coincident with the plane. of the associated arm of the intermediate portion 10 as shown in Figure 3. Each flange 14 has a central open1ng16 to loosely receive the adjacent end of the connecting rod 8 or 9, while the yieldable end extensions 15 are formed with central longitudinal elongated slots 17 to permit the freepassage of the connecting rods 8 or 9 .therethrough. It will be particularly noted that the ear 14 of. the upper horizontal arm of the corner iron is relatively short so that the end of the connecting.

rod passed therethrough will be-positioned close to the upper arm of the corner iron. A nut 18' is applied to-the threaded adjacent end of the connecting rod 8 outwardly of' the ear 14, and a flat face of this nut will engage the'upper' arm of the angular intermediate portlon 10 of the corner iron so as to be held against rotation relative to the connecting rod 8. By providing the rod 8 with 3 oppositely turned or ad usting through the nuts 18' whereby the corner irons may be adjusted and drawn tightly against the sides of the box. As the ears 14 are flexed by thisv adjustment, the free inneror lower ends of the extensions 15 willengage the top of the box soas to thereby be flexed for causing the lowerend walls of the slots17 to engage and bind against the rod 8 for effectively securiiig the latter against turning after being adjusted. Theea-r 14 and extension 15 onthe vertical arm. of the intermediate portion 10 will operate in the same way except that the nut 18 on the upper end of each rod 9 may be freely turned due to the fact that thehut is spaced from the adjacent lower end portion of said vertical armof the intermediate portion 10 as shown in Figure 3. A look washer 19 is accordingly employed tosecure the nut 18 in adjusted position; The lower ends of the side connecting threaded ends, it may be rods 9 preferably have the usual hooks adapted to engage the stake pocket '21 or other suitable securing means.

In use, the pair of'corner irons are connected by the top connecting rod 8 and adjusted to the upper corners of the box 5 as well as toward each other into engagement with the sides of the box. The upper, ends of the connecting rods 9 are then passed through the ears 14 and extensions 15 on the depending arms of the corner irons, and the lowerends of the rods 9 are suitably secured to the floor 6 as at 20. The nuts 18" are then tightened so that the corner irons arefirmly drawn downwardly to efiectively secure the box 5, uponthe floor 6 against objectionable shifting movement or upward, displacement. f

In view of the above 'it will, be seen that the present holding or securing means. will be extremely light in weight although quite strong and eflicient. It will further be apparent that the construction may be readily and economicall manufactured as well as easily and expe itiously placed into practical use.

Minor changes may be made without departing from the spirit and scope of the invention as claimed.

What I claim as new is:

1. Means for securing a box against vertical movement on a floor comprisinga pair of angle grips adapted to fit upon the upper side corners of the box, a; rod adapted to extend across the to of. the box and connecting said angle grips, and other rods for connecting'the angle grips to the floor to secure the box thereon. p
